【発明の属する技術分野】
本発明は、引戸用鎌錠のストライクに関する。
【０００２】
【従来の技術】
引戸用の鎌錠（戸先錠）は、引戸の縦框に取り付けられる。この鎌錠は錠ケース内にシリンダーダルマ又はサムターンダルマの駆動力によって掛合方向へと出没自在に回転する鎌片を備えている。一方、鎌片が係脱するストライクは、引戸用の戸枠に適宜に組込まれている。
【０００３】
この種の戸先錠（鎌錠）を有する引戸は、戸枠に嵌め込む場合に、地震などの揺れを考慮し、普通一般に若干の間隙を設けている。この間隙は、例えば１ｍｍ〜５ｍｍ程度である。このような場合、引戸を閉じた際に鎌片は、戸枠と引戸との間隙の大小に拘わらず、いわゆるガタがなく掛合部材に係止されるのが望ましい。
【０００４】
一方、引戸如何によっては、いわゆる跳ね返り現象が生じる場合がある。このような場合に於いて、しばしば若干の隙間があるのにも拘わらず、鎌片をストライクの掛合部材に掛け合わせる時がある。このような時、シリンダーダルマ又はサムターンダルマを強制的に回すのではなく、引戸を単に閉めるだけで所望の掛合状態を達成することができれば問題はない。
【０００５】
そこで、現在、複雑な構成を採用することなく、上述した幾つかの要望を満たすことができる引戸用鎌錠のストライクの出現が期待されている。
【０００６】
【発明が解決しようとする課題】
本発明の第１の目的は、戸枠と引戸との間隙の大小に拘わらず、鎌片をいわゆるガタなく掛合部材に係止させることができることである。第２の目的は、引戸を閉めた場合に於いて、戸枠と引戸との隙間が大き過ぎた時、シリンダーダルマ又はサムターンダルマを強制的に回すのではなく、引戸を単に閉めるだけで所望の掛合状態を達成することができることである。第３の目的は、構成する部品点数を少なくすることである。第４の目的は、鎌錠装置の取り付け作業の効率化を図ることができることである。
【０００７】
【課題を解決するための手段】
本発明の引戸用鎌錠のストライクは、ストライク本体１６内に二股状の連動部材２０を、固定軸４５を介して軸支し、この連動部材２０の一方の部位４８にはストライク本体１６内に昇降動自在に設けられたブロック状の掛合部材１９を係合させ、一方、連動部材２０の他方の部位には可動軸２１及び長孔４０を介して縦長板状の作動部材３５の一端部を連結し、この作動部材３５の他端部は、横軸３６を介して軸支されていると共に、ストライク本体１６内に装備された付勢バネ２２により該作動部材３５の一端部側が常時前面板１８側に位置するように付勢され、前記掛合部材１９は引戸１を閉めた際戸枠１５と引戸との間に若干の隙間ａが生じていても、該引戸１をさらに引き寄せると、鎌片８の先端部８ａに押圧されて所定方向に揺動する前記作動部材３５及び該作動部材３５に連動して反対方向へ多少回転する前記連動部材２０を介して移動し、該掛合部材１９に形成された係合部２７は、鎌片８の先端部８ａと係合することを特徴とする。
【０００８】
【発明の実施の形態】
図１乃至図６により本発明の実施形態の第１実施例を説明する。まず１は鎌錠Ｘを有する引戸、２は引戸１の縦框に内装された錠ケースで、該錠ケース２は鎌錠Ｘの構成の一部を成す。３は錠ケースの開口部４側に固定されたフロント、５は制御部材の一例としてのサムターン本体、６はサムターンダルマ、７は制御部材によって制御される駆動部材、８は駆動部材によって回転する鎌片である。なお、前記制御部材５，６と駆動部材７は、説明の便宜上の区分けに過ぎないので、両部材を制御又は駆動部材と称しても良い。
【０００９】
次に前記各部材について簡単に説明する。引戸１は、本実施例では「戸先錠」と称されるものを意味する。したがって、錠ケース２に出没自在に設けられた鎌片８は、戸枠側に設けられたストライクＹの掛合部材１９に係脱する。錠ケース２は、室内側に仮想線で示すサンターン本体５を、一方、室外側にキーによって回転する図示しないシリンダーを備えている。サムターンダルマ６は中心部に係合孔を有すると共に、その同芯円上の一部に制御ギヤ６ａが設けられている。駆動部材７はサムターンダルマ６と鎌片８との間に介在し、かつ、錠ケース２に横設軸架された固定横軸９に軸支されている。駆動部材７は半径方向へ多少突出する駆動腕７ａ及び前記制御ギヤ６ａに噛合するセクターギヤ７ｂを有している。
【００１０】
鎌片８は、固定支軸１０に軸支され、フロント３から突出する先端部８ａ、該先端部に連設する首部８ｂ、該首部に連設する後端部８ｃに区分けされている。鎌片８の後端部８ｃには案内長孔１１が形成され、該案内長孔１１には駆動部材の駆動ピン１２が遊嵌合している。このように引戸１には錠ケース，制御部材，駆動部材，鎌片などから構成されている鎌錠Ｘが設けられている。
【００１１】
一方、戸枠１５には鎌片の受け部材であるストライクＹが取付けられている。このストライクＹは、本実施例では、ケース状固定枠１７及び該固定枠１７の開口部に固定された前面板１８とから成るストライク本体１６と、このストライク本体１６内に前面板１８に沿って摺動自在に設けられた掛合部材１９と、この掛合部材１９を上下動させる二股状の連動部材２０と、この連動部材２０に一端部が可動軸２１を介して連結され、かつ、鎌片に押圧されて揺動する作動部材３５と、この作動部材３５の一端部が常時前面板１８側に位置するように（前面板に接近する位置，又は前面板に接触する位置などの意味合い。）付勢する付勢バネ２２とから構成されている。
【００１２】
そこで、本発明の主要部について説明する。まず掛合部材１９は、図２で示すようにやや肉厚のブロック体である。このブロック体１９は、図１を基準にすると、ストライク本体１６の前面板１８の内壁面と面接触する垂直スライド前面１９ａを有する。またこの垂直スライド前面１９ａと交差する後部水平面（図２を基準にすると上部面に相当）１９ｂを有する。また後部水平面１９ｂ及び垂直スライド前面１９ａに交差する左右の側壁面１９ｃ，１９ｃを有する。また図２で示すように垂直スライド前面１９ａの下端部寄りの左右縁部は、左右の側壁面１９ｃ，１９ｃから突出し、これらの摺動凸条２４，２４は、ストライク本体１６の固定枠左右側壁部１７ｂ，１７ｂに形成した案内切欠部２５，２５にそれぞれ係合している。また左右の側壁面１９ｃ，１９ｃの上端部には、突起状の短軸２６，２６が設けられている。
【００１３】
そして、台板状のブロック体１９の先端部（図２では下端部に相当）には、段差状係合部２７が形成されている。この段差状の係合部２７は、掛合時引戸１の閉止位置や引戸の引き寄せに対応して鎌片８の先端部８ａと接触する。なお、３２はストライク本体１６に形成された鎌片用窓で、この鎌片用窓３２の開口幅は、掛合部材１９の係合部２７の係合幅を考慮してやや幅広に形成されている。
【００１４】
次に作動部材３５はストライク本体１６内に縦長に装備されている。作動部材３５は、前述したようにその一端部３５ａは可動軸２１を介して左右一対の連動部材２０，２０に軸支され、一方、他端部３５ｂは、ストライク本体１６内の適宜箇所、本実施例ではストライク本体１６の下部寄りの部位に横設軸架された横軸３６に枢支されている。
【００１５】
作動部材３５は、図２で示すように端面コ字型状の長枠板に形成され、縦長板状の鎌片受け部３７と、この鎌片受け部３７の左右の縁部を略９０度折り曲げて形成された左右一対の縦長軸受け部３８，３８とを有する。
【００１６】
そして、前記鎌片受け部３７の上部寄りの部位には、前面板１８側に鎌片の先端部８ａと当接可能な幅広状突起部３９が形成されている。また前記縦長軸受け部３８，３８の上端（一端）部には、可動軸２１が貫通する長孔４０，４０が形成され、一方、その下端（他端）部には、横軸３６が貫通する軸孔４１，４１が形成されている。
【００１７】
付勢バネ２２は、一例としてねじりコイルバネが使用されている。しかして、中央部２２ａは横軸３６に設けられていると共に、一端部２２ｂは前面板１８の内壁面に、一方、他端部２２ｃは作動部材３５の他端部３５ｂにそれぞれ圧接する。
【００１８】
掛合部材１９と作動部材３５に介在する左右一対の連動部材２０は、全体としてＬ型状或いは二股状に形成された板部材である。これらの連動部材２０の一部は、作動部材３５の軸受け部３８，３８と掛合部材１９の左右の側壁面との間にそれぞれ組込まれ、かつ、ストイク本体１６の固定枠１７に横設軸架した固定軸４５に揺動可能に軸支されている。
【００１９】
しかして、図２を基準にすると、４６は上端部に形成された固定軸用枢支孔、４７は下端部に形成された可動軸用貫通小孔、４８は掛合部材１９の短軸２６と挟み状に係合する係合指部である。なお、符号５１は固定枠１７に形成された横軸用の貫通孔、５２は固定軸用の貫通孔である。
【００２０】
上記構成においては、引戸１と戸枠１５との間に若干の隙間ａ、例えば５ｍｍ，３ｍｍ，１ｍｍがあっても、つまり、引戸１を閉めた場合において、引戸１と戸枠１５との間に若干の隙間ａがあっても、間隙ａの大小に拘わらず、ガタなく鎌片８をストライク本体１６の前面板１８や掛合部材１９に選択的に係止させることができる（図３，図４,図６参照）。
【００２１】
図３は引戸１を閉じた時、隙間ａが、例えば５ｍｍ程度ある場合を想定した説明図である。この場合鎌片８が制御部材（サムターンダルマ，シリンダーダルマ等）５及び駆動部材７の駆動力により固定支軸１０を支点に時計方向へ回転すると、まず先端部８ａがストライクＹの窓３２に入り込み、次いで先端部８ａの弧状外周面が鎌片受け部３７の幅広状突起部３９に回転状態で摺接し始める。この時ストライクＹ内に入り込んでくる先端部８ａにより作動部材３５の突起部３９は押圧されることになるから、作動部材３５は鎌片８の押圧状態に対応し、かつ、付勢バネ２２のバネ力に抗して横軸３６を支点に多少反時計方向へ揺動する。作動部材３５が反時計方向へ揺動すると、連動部材２０は固定軸４５を支点に時計方向へと多少回転することになるから、掛合部材１９は案内切欠部２５に案内されて多少下方へと下降する。
【００２２】
その結果、鎌片８の先端部８ａは、作動部材３５に押された状態でストライク本体１６の前面板１８の内壁面に係止される。また、本実施例では下降した掛合部材１９の傾斜状下端面２８が多少当接する。
【００２３】
ところで、本実施例では、鎌片８の先端部８ａが傾斜状下端面２８に当たっているが、これは係止条件ではない。この場合の係止条件は、鎌片８が固定支軸１０を支点に完全施錠の位置まで回転したこと、鎌片８の先端部８ａが前面板１８の内壁面１８ａに係止されること、そして、鎌片８は作動部材３５に押圧されていることである。
【００２４】
図４は、引戸１を閉じた時に於いて、隙間ａが、例えば３ｍｍ程度ある場合を想定した説明図である。３ｍｍ程度になる条件としては、（１）引戸１を閉じた時の間隙ａが３ｍｍ程度である場合、（２）図３の間隙状態から引戸１を多少引き寄せた場合がある。
【００２５】
そこで、ここでは前記（２）の場合について説明する。今仮に引戸１を３ｍｍ程度まで引き寄せると、鎌片８はそのままの状態でストライクＹの奥に多少入り込むことになる。この時作動部材３５は鎌片８に押圧されると、前述したように付勢バネ２２のバネ力に抗して横軸３６を支点に反時計方向へとさらに揺動する。作動部材３５が反時計方向へ揺動すると、連動部材２０は固定軸４５を支点に時計方向へと多少回転することになるから、掛合部材１９は案内切欠部２５に案内されて多少下方へと下降する。
この作用について付言すると、掛合部材１９は、引戸１を閉めた際、戸枠１５と引戸との間に若干の隙間ａが生じていても、該引戸１をさらに引き寄せると、鎌片８の先端部８ａに押圧されて所定方向に揺動する前記作動部材３５及び該作動部材３５に連動して反対方向へ多少回転する前記連動部材２０を介して移動し、該掛合部材１９に形成された係合部２７は、鎌片８の先端部８ａと係合する。
【００２６】
その結果、鎌片８の先端部８ａは、作動部材３５に押された状態でストライク本体１６の前面板１８の内壁面１８ａから、今度は掛合部材の係合部２７の係止面２７ａに移行係合する。
【００２７】
図６は鎌片８がさらにストライクＹの奥に入り込んだ場合を示す。この場合作動部材２５、連動部材２１及び掛合部材１９の作動態様は、図４の場合と同様である。
【００２８】
１ｍｍ程度になる条件としては、（１）引戸１を閉じた時の間隙ａが１ｍｍ程度である場合、（２）図３又は図４の間隙状態から引戸１を多少引き寄せた場合がある。
【００２９】
しかして、引戸１を１ｍｍ程度まで引き寄せた場合には、鎌片８の先端部８ａは、作動部材３５に押された状態で前面板１８の内壁面１８ａ又は掛合部材の係合部２７(係止面２７ａ)から掛合部材１９の下端部の背面２７ｂへと移行係合する。したがって、本実施例では鎌片８が掛合部材１９の背面２７ｂに圧接するのも掛合或いは係合態様の一例である。
【００３０】
このように、本実施例では引戸１の引き寄せが可能な場合にも、鎌片８は隙間（引戸の閉鎖位置）ａに対応してガタなく前面板１８乃至掛合部材１９の下端部に係合する。
【００３１】
【実施例】
本実施例では、掛合部材１９の下端部に形成された係合部２７は段差状であるが、階段状に形成しても良い。また設計如何によっては前記係合部２７を傾斜状に形成し、一方、これに係止される鎌片の先端部８ａを、前記係合部２７に対して接線方向に摺接するようにテーパ状に形成しても良い。さらに、掛合部材１９の係合部２７は、図１を基準にすると下向きであるが、これは鎌片８との係合関係を考慮したものである。したがって、鎌片８の取付け如何によって鎌片８の先端部８ａが下向きに係合する場合には、当然掛合部材８等の取付け位置（向き）も変わる。
【００３２】
【発明の効果】
以上の説明から明らかなように、本発明にあっては、次に列挙するような作用・効果がある。
（１）引戸を閉じた際に間隙ａがあっても、鎌片は間隙ａの大小に拘わらず、いわゆるガタがなく、ストライク本体の前面板や掛合部材の下端部（他端部）に係止される。
（２）引戸をさらに引き寄せることが可能な場合（例えば間隙が１ｍｍ程度までＯＫの場合）には、引戸を単に手で引き寄せることが可能である。この場合掛合部材の掛合面が段差状或いは傾斜状に形成されているので、隙間を所望する位置まで小さくすることができる。
（３）構成する部品点数を少なくすることができる。
（４）鎌錠装置の取り付け作業の効率化を図ることができる。
（５）主たる構成部材３５，２０，１９がそれぞれシンプルな構成で合理的かつスムースに作動する。

BACKGROUND OF THE INVENTION
The present invention relates to a strike of a sickle lock for sliding doors.
[0002]
[Prior art]
A sickle lock (door lock) for a sliding door is attached to a vertical fence of the sliding door. This sickle lock is provided with a sickle piece that rotates freely in the engagement direction by the driving force of a cylinder dharma or thumb turn dharma in a lock case. On the other hand, the strike on which the sickle piece is engaged and disengaged is appropriately incorporated in a door frame for sliding doors.
[0003]
Sliding door with this kind of door end tablets (Kamajo), when Komu fitted into the door frame, taking into account the shaking of an earthquake, it is provided with a slight gap to the ordinary general. This gap is, for example, about 1 mm to 5 mm. In such a case, it is desirable that when the sliding door is closed, the sickle piece is locked to the engaging member without so-called play regardless of the size of the gap between the door frame and the sliding door.
[0004]
On the other hand, depending on the sliding door, a so-called rebound phenomenon may occur. In such a case, there are times when the sickle piece is hung on the strike engagement member, despite the fact that there is often a slight gap. In such a case, there is no problem as long as the desired engagement state can be achieved by simply closing the sliding door, instead of forcibly turning the cylinder dharma or thumb turn dharma.
[0005]
Therefore, the appearance of strikes for sickle locks for sliding doors that can satisfy some of the above-mentioned demands without adopting a complicated configuration is currently expected.
[0006]
[Problems to be solved by the invention]
The first object of the present invention is that the sickle piece can be locked to the engaging member without so-called looseness regardless of the size of the gap between the door frame and the sliding door. The second purpose is that when the sliding door is closed and the gap between the door frame and the sliding door is too large, it is not necessary to forcibly turn the cylinder dharma or thumb turn dharma. The engagement state can be achieved. A third object is to reduce the number of components to be configured. A fourth object is to improve the efficiency of attaching the sickle lock device.
[0007]
[Means for Solving the Problems]
In the strike of the sickle lock for sliding doors of the present invention, a bifurcated interlocking member 20 is pivotally supported in the strike body 16 via a fixed shaft 45, and one portion 48 of the interlocking member 20 is placed in the strike body 16.

In the above configuration, even if there is a slight gap a between the sliding door 1 and the door frame 15, for example, 5 mm, 3 mm, 1 mm, that is, when the sliding door 1 is closed, Even if there is a slight gap a, the sickle piece 8 can be selectively locked to the front plate 18 and the engaging member 19 of the strike body 16 without any play regardless of the size of the gap a (FIGS. 3 and 3). 4, see FIG.
[0021]
FIG. 3 is an explanatory diagram assuming that the gap a is, for example, about 5 mm when the sliding door 1 is closed. In this case, when the sickle piece 8 is rotated clockwise around the fixed support shaft 10 by the drive force of the control member 5 (thumb-turn dharma, cylinder dharma, etc.) 5 and the drive member 7, the tip 8a first enters the window 32 of the strike Y. Then, the arc-shaped outer peripheral surface of the tip end portion 8a starts to slidably contact the wide protrusion 39 of the sickle piece receiving portion 37 in a rotating state. At this time, the protrusion 39 of the operating member 35 is pressed by the tip 8a entering the strike Y, so that the operating member 35 corresponds to the pressing state of the sickle piece 8 and the biasing spring 22 It swings slightly counterclockwise about the horizontal shaft 36 against the spring force. When the actuating member 35 swings counterclockwise, the interlocking member 20 slightly rotates clockwise with the fixed shaft 45 as a fulcrum, so that the engaging member 19 is guided to the guide notch 25 and slightly downward. Descend.
[0022]
As a result, the tip 8 a of the sickle piece 8 is locked to the inner wall surface of the front plate 18 of the strike body 16 while being pressed by the operating member 35. Further, in the present embodiment, the inclined lower end surface 28 of the lowering engaging member 19 comes into contact with each other somewhat.
[0023]
By the way, in the present Example, although the front-end | tip part 8a of the sickle piece 8 has contacted the inclined lower end surface 28, this is not a locking condition. The locking conditions in this case are that the sickle piece 8 has been rotated to the fully locked position with the fixed support shaft 10 as a fulcrum, that the tip 8a of the sickle piece 8 is locked to the inner wall surface 18a of the front plate 18, The sickle piece 8 is pressed by the operating member 35.
[0024]
FIG. 4 is an explanatory diagram assuming a case where the gap a is, for example, about 3 mm when the sliding door 1 is closed. The conditions to be about 3 mm include (1) when the gap a when the sliding door 1 is closed is about 3 mm, and (2) when the sliding door 1 is slightly pulled from the gap state of FIG.
[0025]
Therefore, here, the case (2) will be described. If the sliding door 1 is pulled to about 3 mm now, the sickle piece 8 will enter the depth of the strike Y to some extent. At this time, when the actuating member 35 is pressed against the sickle piece 8, as described above, the actuating member 35 further swings counterclockwise about the horizontal shaft 36 against the spring force of the biasing spring 22. When the actuating member 35 swings counterclockwise, the interlocking member 20 slightly rotates clockwise with the fixed shaft 45 as a fulcrum, so that the engaging member 19 is guided to the guide notch 25 and slightly downward. Descend.
In addition to this action, when the sliding member 1 is closed, when the sliding door 1 is closed, the hooking member 19 is further pulled toward the tip of the sickle piece 8 even if a slight gap a is generated between the door frame 15 and the sliding door. The engagement member 19 is moved by the engaging member 19 that is pressed by the portion 8a and moves in the predetermined direction and the interlocking member 20 that is slightly rotated in the opposite direction in conjunction with the operation member 35. The joint portion 27 engages with the tip portion 8 a of the sickle piece 8.
[0026]
As a result, the tip portion 8a of the sickle piece 8 is shifted from the inner wall surface 18a of the front plate 18 of the strike body 16 to the locking surface 27a of the engaging portion 27 of the engaging member while being pushed by the operating member 35. Engage.
[0027]
FIG. 6 shows a case where the sickle piece 8 further enters the back of the strike Y. In this case, the operation modes of the operating member 25, the interlocking member 21, and the engaging member 19 are the same as in the case of FIG.
[0028]
The conditions to be about 1 mm include (1) when the gap a when the sliding door 1 is closed is about 1 mm, and (2) when the sliding door 1 is slightly pulled from the gap state of FIG. 3 or FIG.
[0029]
Thus, when the sliding door 1 is pulled to about 1 mm, the distal end portion 8a of the sickle piece 8 is pushed by the actuating member 35, and the inner wall surface 18a of the front plate 18 or the engaging portion 27 (engagement portion 27) of the engaging member. From the stop surface 27a), it is engaged in transition to the back surface 27b of the lower end portion of the engaging member 19. Therefore, in this embodiment, the sickle piece 8 is in pressure contact with the back surface 27b of the engaging member 19 is an example of the engaging or engaging manner.
[0030]
As described above, in this embodiment, even when the sliding door 1 can be pulled, the sickle piece 8 engages with the front plate 18 or the lower end portion of the engaging member 19 without any play corresponding to the gap (closing position of the sliding door) a. To do.
[0031]
【Example】
In this embodiment, the engaging portion 27 formed at the lower end portion of the engaging member 19 has a step shape, but may be formed in a step shape. Further, depending on the design, the engaging portion 27 is formed in an inclined shape, and on the other hand, the tip portion 8a of the sickle piece locked thereto is tapered so as to slidably contact the engaging portion 27 in the tangential direction. You may form in. Further, the engaging portion 27 of the hooking member 19 is downward with reference to FIG. 1, but this is in consideration of the engaging relationship with the sickle piece 8. Therefore, when the tip 8a of the sickle piece 8 is engaged downward depending on whether the sickle piece 8 is attached, the attachment position (orientation) of the engaging member 8 and the like naturally changes.
[0032]
【The invention's effect】
As is clear from the above description, the present invention has the following actions and effects.
(1) Even if there is a gap a when the sliding door is closed, the sickle piece does not have a so-called backlash regardless of the size of the gap a, and is not related to the front plate of the strike body or the lower end (other end) of the engaging member. Stopped.
(2) When the sliding door can be further pulled (for example, when the gap is OK up to about 1 mm), the sliding door can be simply pulled by hand. In this case, since the engaging surface of the engaging member is formed in a stepped shape or an inclined shape, the gap can be reduced to a desired position.
(3) The number of components can be reduced.
(4) The efficiency of attaching the sickle lock device can be improved.
(5) The main constituent members 35, 20, and 19 operate rationally and smoothly with simple configurations.
